== Use cases ==

* Search for 'missing' aliquot data. Specifically, search for all specimen under a range of participant IDs where the specimen place holder isn't populated:
  *Simple search: 
    * Specimen Collection Group / Protocol Participant Identifier STARTS WITH "9" ("9" is first character of all Northampton lab IDs)
    * Specimen / Label IS NULL (NULL indicates the label doesn't exist, which is a mandatory field so this searches for missing data only)
